ios - IOS 中的 HTTPS post 请求

Question

我正在尝试使用以下代码发出 https 发布请求。

NSURL *url = [NSURL URLWithString:@"https://portkey.formspring.me/login/"];

//initialize a request from url
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[url       standardizedURL]];

//set http method
[request setHTTPMethod:@"POST"];
//initialize a post data

NSDictionary *postDict = [NSDictionary dictionaryWithObjectsAndKeys:@"username", @"username",
                          @"password", @"password", nil];

NSError *error=nil;

NSData* jsonData = [NSJSONSerialization dataWithJSONObject:postDict
                                                   options:NSJSONWritingPrettyPrinted     error:&error];



[request setValue:@"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

//set post data of request
[request setHTTPBody:jsonData];

//initialize a connection from request
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

//start the connection
[connection start];

但我收到以下回复。

error Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “portkey.formspring.me” which could put your confidential information at risk." UserInfo=0x7564180 {NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, NSErrorFailingURLKey=https://portkey.formspring.me/login/, NSLocalizedDescription=The certificate for this server is invalid.

谁能告诉我如何使用 NSURLConnection 发出发布请求？

提前致谢。

您尝试连接的网站的证书不受信任(请尝试访问您在 Chrome 中发布的链接)。

默认情况下，iOS 不允许您连接到提供不受信任证书的站点。如果绝对必要，您可以绕过此检查 - 请参阅此问题:How to use NSURLConnection to connect with SSL for an untrusted cert?

但是，实际修复有问题的证书会好得多。
